TLDR
Thebaine (VII) has been degraded to (−)-cis-[2-methyl-2-carboxy-cyclohexyl-(1)]-acetic acid (III), thus providing experimental proof of the absolute configuration of morphine, thebaine and related alkaloids as discussed by the authors.

The Chemistry and Pharmacology of Morphinan Alkaloids

A. Brossi
TL;DR: The chemistry of morphinan drugs is closely related to that of morphine through recognition of its structure by Robinson and Sugasawa (1933) and Schopf and Thierfelder (1939) as discussed by the authors.

Structure and reactions of photothebainehydroquinone

TL;DR: The structure of photothebainehydroquinone was shown by X-ray crystallography to be 3a, which arises from 2 through a di-π-methane to vinylcyclopropane rearrangement as mentioned in this paper.

Untersuchungen über asymmetrische Synthesen III. Über die Anwendung der asymmetrischen Synthese zur Konfigurationsbestimmung bei Triterpenen und Steroiden

TL;DR: In this article, the erwahnten Triterpene and Steroide mit 30 Kohlenstoffatomen die gleiche Konfiguration und Konstellation im Ringe A besitzen, wie die Abkommlinge des Cholestanols-(3β), dessen absolute Konfigureuration mit Hilfe der asymmetrischen Synthese indirekt bestimmt wurde.
